UNITED STATES PATENT OFFICE.

CHARLES SMITHSON AND JOI-IN W. OSBORNE, OF WINCI-IESTER, ILLINOIS; SAIDOSBORNE ASSIGNOR TO SAID SMITI-ISON.

INSULATOR.

To all whom it may concern:

Be it known that we, CHARLES SMrrnsoN and JOHN WV. OsBoRNn, citizens ofthe United States, residing at W'inCheSter, in the county of Scott andState of Illinois, have invented certain new and useful Improvements inInsulators; and we do declare the following to be a full, clear, andexact de scription of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to an insulator for telegraph or telephone wiresand has for its object to provide a form of insulator by means of whichthe tie wires may be dispensed with and which will withstand stormswithout breaking.

Vith this and other objects in view, the invention consists of certainnovel features of construction, combination and arrangement of parts aswill be more fully described and particularly pointed out in theappended claims.

In the accompanying drawings: Figure 1 is a side elevation of aninsulator embodying our improvements; F ig. 2 is a central longitudinalsection of the upper portion thereof with the clamping lugs turned up;Fig. 3 is a vertical transverse section; and, Fig. 4 an inverted planview showing the interior of the hood.

Referring to the drawings for a more particular description of theinvention the insulator comprises a hood 1 of frusto-pyramidal formhaving the outwardly inclined sides and ends 2 and 3 respectively.

4 indicates the insulator support which comprises a flat body which isadapted to t within the hood and a central cylindrical stem 5 having anouter eXteriorly threaded portion 6 adapted to screw into a suitablesupport. The body 4 of the support is insulated from the hood byinterposed strips of mica 7 or other suitable insulating materialtherebetween while the support is held within or secured to the hood bymeans of the clamping lugs 8 which are formed by portions of the sideand end walls thereof and are bent upwardly against the bottom face ofsaid body. The hood is provided with a plurality of vertical pins 9which are notched out to receive the wire.

Specification of Letters Patent.

serial No. 519,177.

From the foregoing it will be seen that our insulator may be quicklyadjusted in position and when so adjusted will weather severe stormswithout breaking.

From the foregoing description taken in connection with the accompanyingdrawings, the construction and operation of the invention will bereadily understood without requiring a more extended explanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacricing any of the advantages of this invention as dened in theappended claims.

`We claim as our invention.

1. An insulator comprising a hood, a support comprising a flat bodyadapted to fit within the hood and acentral eXteriorly threaded stem,strips of insulating material interposed between the head and the bodyof the support and means for clamping the body of the support inposition.

2. An insulator of the class described comprising a hood, a supportcomprising a flat body adapted to fit within the hood and a centraleXteriorly threaded stem, insulating material interposed between thebody of the support and the hood and clamping lugs formed at oppositeends and sides of the hood and adapted to be bent inwardly against thebody of the support.

8. An insulator of the class described comprising a hood havingoutwardly inclined sides and ends, a support consisting of a flat bodyadapted to fit within the hood, and a central eXteriorly threaded stem,insulating material interposed between the body of the support and thehood and lugs formed on opposite sides and ends of the hood and adaptedto be bent inwardly against the body of the support.

In testimony whereof we have hereunto set our hands in presence of twosubscribing witnesses.
